AUTOMOBILE SPRING.

APPLICATION TILED OUT. 9, 1909.

' tween the sliding blocks 12, 12 and the to the bolt or piulil at the end of the lower return movements of the blacks 12 relathat I could use rubber Washers or any other around each of the bolts 17 are placed be blocks 18, 18*. These springs 24c serve to receive and to cushion the sudden upward movements of the lovverblocks 12, 12 and of the automobile body which is connected thereto through the spring 6.

The operation of my improvements is substantially as follows: The Weight of the body of the automobile and the load which it carries is transmitted throu h the elliptic side spring 6 to the lower sliding blocks '12,

The side spring 6. being pivotally attached to these blocks by meansz'of a bolt 10, the said Weight is transmitted, as above described, in any of the various angular po 'sitions which the parts may assume. The said Weight is then transmitted to the spiral springs 13 and they in turn transmit the Weight to the plate 15, Which in lllllll transmits said Weight to the heads of the bolts 17. The bolts 17 carry the weight to the blocks 18 and 18 which finally give it elliptic side spring 7.

It Will be seen that the Weight, of the automobile body and its load is at all times carried by'the additional springs 13 and a greater resilient client is thus produced.

An important effect of my construction lies'in the" sliding engagement of the bolts 17 in the blocks 12, 12 by which means the blocks 18, 1 8 and the blocks 12, 12 are constrained to move in alinement. It Will, therefore, be seen that. relative lateral movement of the ends of the upper elliptic spring 6 and lOWGl elliptic spring 7 is prevented. l Vhile the above described lateral movement is prevented, my'improved construction does not in any Way interfere With the longitudinal swinging movements of the parts. The combination of parts which compose my improvements, taken as a Whole, serve a swinging link for connecting the said ellip tic springs. They have the further advantage of resiliency While serving as a simple link.

'llhssmalier springs 24.- provide a very de sirable cushioning etlect in arrest ng sudden tively tothe blocks 18, 18 It is evident suitable form of buffer in place of the springs 24;

ldfhile l have described more or less precisely the details of construction, I "do not wish to be understood as limiting myself thereto, as. l contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit of my invention.

1 claim:

1. The combination with the two members of a vehicle elliptical spring, of two pairs of vertical guides, means for'secu'ring the end or the lower member of thespring betwecnfthe pairs of guides, two pairs of sleeves surrounding said guides, means for-fpiyotally supporting the end or" the upper member of the spring between. and directly by the pairs of sleeves, a plate secured to the lower ends member oi the spring between said second pair of blocks, coiled springs surrounding said guides beneath said second pair 0t blocks, and means on said guides for supporting the lower ends of the coiled springs.

3. The (:Ofllblnillllfllfflltll the two members of a vehicle elliptical spring, of a pair of blocks between which one end of one member of the spring is pivotally secured, a pair of guides rigidly connected to and depending from each block, a second pair of blockshaving extended sliding engagements with the corresponding pairs of guides, means for pivotally connecting the end the other,

member of the spring between said second pair of blocks, coiled springs surrounding said guides beneath said second pair of blocks, means on said guides for supporting the lower ends of the coiled springs, and coiled springs surrounding said guides intermediate of the upper and lower pairs of locks.

In testimony whereof, I have subscribed my name.
